You should align the partition to a 4K boundary. 1MB happens to be what was settled upon (and with 50+GB for a small SSD, what's the loss of 1MB, right?), but 4K is the really important one.We got SSDs at work (XP), just plugged it in, cloned the HDD to the new SSD and had zero issues. Though I did read after that you should leave a 1MB space at the start for better performance, and we did not do this, but it's still 10x better than it was before. It used to take about 45 minutes to an hour to be up and running and now it takes about 5-10 minutes. (most of that waiting is waiting on the network and not the PC)
